Gov. Dayton tells MPR that Amy Koch's apparent affair with a staffer makes it hard for Republicans to claim the moral high ground when it comes to marriage. He says he hopes the party will reconsider a constitutional amendment that would restrict marriage to opposite-sex couples.

Supporters of the constitutional marriage amendment have filed a lawsuit asking the Minnesota Supreme Court to change the ballot title question back to “Recognition of marriage solely between one man and one woman." Last month, Secretary of State Mark Ritchie and Attorney General Lori Swanson changed the tittle voters will see in November to “Limiting the status of marriage to opposite sex couples.”

Jewish Community Action used a Minnetonka event to rally opposition to the marriage amendment that will appear on Minnesota's ballot this fall. One of the group's leaders says the amendment, which would ban same-sex marriage, is contrary to the values of the Torah. Not all rabbis agree, though.

Obama's Minnesota campaign team on Monday said the president opposes a constitutional amendment that would limit marriage to opposite-sex couples. "While the President does not weigh in on every single ballot measure in every state, the record is clear that the President has long opposed divisive and discriminatory efforts to deny rights and benefits to same sex couples," a spokeswoman said.

Secretary of State Mark Ritchie has submitted the title “Limiting the Status of Marriage to Opposite Sex Couples" to Attorney General Lori Swanson for final approval, the Associated Press reports. Supporters of the constitutional amendment want it titled, "Recognition of Marriage Solely Between One Man and One Woman."

Campaign finance records show Rev. Peter Lambert of St. Louis Catholic Church, about 45 miles west of Duluth, donated $1,000 about six months ago to Minnesotans United for All Families -- the primary group fighting the controversial ballot measure to essentially ban same-sex marriage in Minnesota. The News Tribune reports no other Minnesota priest in a recognized diocese has contributed to any group trying to defeat the constitutional amendment.

With a healthy lead in the polls, Sen. Amy Klobuchar, D-Minn., is spending some of her political capital in the divisive fight over the marriage amendment. In a new email to potential donors, Klobuchar says she has pledged to help raise $10,000 for the fight against the controversial state ballot measure that would define marriage as between a man and woman.

Opponents and supporters of the proposed marriage amendment set up shop at the Minnesota State Fair. On Wednesday, Augsburg College took a public stance opposing the amendment.
